Homemade Dishwasher Detergent 1 cup Borax 1 cup Washing Soda Citric Acid 1/2 cup Kosher Salt (I used Sea Salt.... not sure if it would differ to use Ionized Salt or not...) 1 tsp White Rice (you don't need to do this but it helps the batch from not clumping due to to citric acid. It won't hurt your dishwasher at all)
